Answer:

The complex conjugate of #3i# is #(-3i)#

Explanation:

The complex conjugate of a number is another number with a real component equal to the original number and an imaginary component equal in magnitude but with the opposite sign.

#color(red)("real")+color(blue)("imaginary")#

#color(blue)(3i) = color(red)(0)+color(blue)(3i)#

So the complex conjugate is
#color(red)(0) + color(blue)((-3i)) = color(blue)(-3i)#
